server, or visit the IBM® Director Information Center at http:// publib.boulder.ibm.com/infocenter/director/v6r1x/index.jsp. Information LED: When this amber LED is lit, it indicates that information about a system event in the blade server has been placed in the Advanced-ManagementModule event log. The information LED can be turned off through the Advanced-Management-Module CLI, SNMP, or Web interface or through IBM® Director Console. For more information about the Advanced-Management-Module Web interface, see http://www.ibm.com/systems/management/. For more information about IBM® Director, see the documentation on the IBM® Director CD that comes with the server, or visit the IBM® Director Information Center at http://publib.boulder.ibm.com/infocenter/director/v6r1x/index.jsp. Fault LED: When this amber LED is lit, it indicates that a system error has occurred in the blade server. The blade-error LED turns off only after the error is corrected. Power-control button: Press this button to turn on or turn off the blade server. Note: The power-control button has effect only if local power control is enabled for the blade server. Local power control is enabled and disabled through the Advanced-Management-Module Web interface. NMI button (recessed): The nonmaskable interrupt (NMI) dumps the partition. Use this recessed button only as directed by IBM Support. Note: You can also send an NMI event to the selected blade server remotely using the AMM. For more information, see the BladeCenter Advanced Management Module User's Guide. Keyboard/video/mouse (KVM) select button: Press this button to associate the shared BladeCenter unit keyboard port, video port, and mouse port with the blade server. The LED on this button flashes while the request is being processed and then is lit when the ownership of the keyboard, video, and mouse has been transferred to the blade server. It can take approximately 20 seconds to switch the keyboard, video, and mouse control to the blade server. Using a keyboard that is directly attached to the Advanced-Management-Module, you can press keyboard keys in the following sequence to switch KVM control between blade servers instead of using the KVM select button: NumLock NumLock blade_server_number Enter blade_server_number is the two-digit number of the blade-server bay in which the blade server is installed. A blade server that occupies more than one blade-server bay is identified by the lowest bay number that it occupies. If there is no response when you press the KVM select button, you can use the Advanced-Management-Module Web interface to determine whether local control has been disabled on the blade server. See http://www.ibm.com/systems/ management/ for more information. Notes: 1. The operating system in the blade server must provide USB support for the blade server to recognize and use the keyboard and mouse, even if the keyboard and mouse have PS/2-style connectors. 16 BladeCenter HS22 Type 7870, 1936, and 1911: Installation and User's Guide
